Trial summary

There are many patients hospitalized for chest pain, which don't have high risk features that require invasive coronary angiography, but are considered intermediate risk and for which ischemic heart disease can not be excluded. Read more about this study

About this study

Official title: Sixty Minutes Heart Rate Variability Testing Compared With Non-invasive Exercise Stress Test in Hospitalized Patients With Suspected Angina Pectoris

There are many patients hospitalized for chest pain, which don't have high risk features that require invasive coronary angiography, but are considered intermediate risk and for which ischemic heart disease can not be excluded.

The current management for these patients is to perform a non invasive test in order to classify their risk.

Exercise ergometry is a commonly used non invasive test to detect ischemia. that test is non-invasive, and does not involve radiation or intra-venous contrast. The test is limited for many patients, because of un-ability to exercise, or because of non-interpetable Electro Cardio-Graphy (ECG).

Heart rate variability is well known to be a marker of ischemic heart disease. Heart rate variability testing is a non-invasive ECG monitoring technique.

The study design is to identify hospitalized patients who are candidates for non-invasive stress testing, and to monitor their heart rate variability for one hour prior to the stress test.

Read the detailed description

Ischemic heart disease is among the leading causes of death and disability in the modern world. Effective treatment for cardiac ischemia is based on identification of the proper patients and assigning prompt treatment to those patients.

It is not simple identifying the proper patients. There are many patients complaining of typical anginal chest pain without coronary heart disease, and there are many patients with active angina who complain of non-typical symptoms or who don't feel any symptoms.

Management of hospitalized patients with suspected angina pectoris is based on their complaints, their risk factors and laboratory results (ECG, troponin). They are classified into low-risk, high risk and intermediate.

Intermediate risk patients usually require additional testing in the hospital in order to re-classify them into high or low risk.

Heart rate variability is a well-known marker of active cardiac ischemia. The investigators plan to perform a 60 minute heart rate variability monitoring.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation betwen Heart rate variability test and non-onvasive testing

    Heart rate variability results will be compared to non-invasive test results ordered as routine care by treating physician.

    Measured: The time from non-invasive testing to hospital discharg. Estimated up to 5 Days

Secondary outcomes (1)
  1. Correlation between Heart rate variability and invasive angiography

    Patients which will undergo invasive angiography as part of selected management strategy will be compared with Heart rate variability test results.

    Measured: Time from non-invasive testing to coronary angiography. Estimated up to 5 days

Questions about this trial

What is this clinical trial studying?

An observational study of Angina Pectoris and Ischemic Heart Disease, run by Meir Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yoav Arnson, MD (97297472120, yoav.arnson@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation betwen Heart rate variability test and non-onvasive testing (time frame: The time from non-invasive testing to hospital discharg. Estimated up to 5 Days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02530021, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2016.
